What setting controls whether or not a check box opens in design .

[Bouy]

I am having trouble finding the controls that determine whether an active x
control in a word document opens up in design mode or not. On the template
that I created it opens as it is supposed to on my computer and some other
users computers - however, one some of the other computers the template opens
up in design mode - rendering the check boxes that I put in unusable until
the control is exited from design mode. Any suggestions?

[Jay Freedman]

Any document containing any ActiveX control will open in design mode
if the user's macro security level is set to High (or if it's Medium
and the user clicks Disable in the warning box). The exception is if
the document is digitally signed and the user accepts the certificate.
